Brawl needs rankings/tiers to discourage early scoops
I'm tired of people scooping in Brawl games because they didn't like their first two hands, or because I played turn 1 Ragavan, or because I fatal pushed your turn 1 Ragavan. There's a lot of people who will scoop at the first sign of adversity in the first few turns. It's gotten to the point where I assume my opponent has an unusually strong hand if they stay in the game.
If there was some small penalty to losing, people would be more likely to see if things turn around when they are behind after a couple turns.
EDIT: for the "just take your win, no big deal" crowd, do you think they should get rid of rankings and tiers around every other format, too? If not, why not? What do you think is the purpose of rankings, anyway? Because to me, the main purpose is to encourage both people make a good faith effort to win the game.
